Description

The plastic magnetic drive centrifugal pump with jacket is engineered to ISO2858 standards. Its fluid-contact components feature a composite structure of steel and high-performance plastics (such as fluoroplastics/PTFE), with an intermediate coupling for easy maintenance—simply dismantle the coupling, no need to remove pipelines or the motor.

Performance

  • Flow rate: 1.8 to 400 m³/h
  • Head: 15 to 125 m
  • Maximum operating temperature: 200°C
  • Bearing pressure: 1.6 MPa

Applications

  • Conveying strong corrosive chemical media
  • Transporting organic chemical media and mixed organic/inorganic fluids
  • Chemical, pharmaceutical, food & beverage, water treatment, electronics, and petrochemical industries

Key Features & Advantages

  • Leak-free magnetic drive: Power is transmitted via magnetic coupling, eliminating mechanical seals and the risk of leakage—ideal for volatile, toxic, corrosive, or high-temperature liquids.
  • Jacketed design for temperature control: External jacket regulates pump and fluid temperature using circulating coolant or heating fluid, ensuring safe and efficient operation with high or low temp liquids.
  • Superior corrosion resistance: Fluoroplastic/PTFE construction withstands strong acids, alkalis, solvents, and salt solutions.
  • Hanging structure: No water cooling box needed when conveying high-temperature media; compact and easy to maintain.
  • Energy saving and high efficiency: Magnetic drive system reduces energy consumption and noise during operation.
  • Adaptable to various liquids: Suitable for high temperatures, corrosive fluids, and liquids containing solid particles.
  • Enhanced safety: Jacketed design protects against overheating and flammability risks when handling volatile or hazardous fluids.

Working Principle

  • Magnetic coupling transmission: The external motor’s rotor drives the internal pump rotor through a magnetic field, so no liquid contacts the motor—eliminating leaks.
  • Jacket temperature control: Circulating coolant or heating fluid in the jacket keeps the pump and media at optimal temperature, preventing overheating, freezing, or efficiency loss.

Common Material Selection

  • Fluoroplastics (PTFE): Excellent chemical resistance for strong acids, chlorides, fluorides, and high-temp media.

Maintenance & Precautions

  • Regularly check magnetic drive system for proper power transmission.
  • Ensure fluid circulation in the jacket for effective temperature control.
  • Avoid exceeding recommended operating temperatures, even with jacket protection.
